Abstract (en)
[origin: WO2022254012A1] A conductive polymer dispersion comprising a polythiophene and a polyanion, characterized in that the polyanion is a homo- or copolymer of amonomer unit according to Formula (I), wherein any of R1 to R5 is selected from the group consisting of hydrogen, a halogen, an ether and a substituted or unsubstituted alkyl group with the proviso that at least one of R1 to R5 is a substituent according to Formula (II), wherein L represents a divalent linking group having less than (20) carbon atoms;n represents 0 or 1; R6 and R7 are independently selected from the group consisting of hydrogen, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted alkynyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted alkaryl group and a substituted or unsubstituted aryl or heteroaryl group;any of L, R6 and R7 may represent the necessary atoms to form a 5 to 8 membered ring; M represents hydrogen or a counterion to compensate the negative charge of the sulfonate group;the dashed line represents a covalent bond to the phenyl ring of Formula (I).
